The Scarab Murder Case (1930) is a classic whodunit written by S. S. Van Dine. In this book, detective Philo Vance's murder investigation takes place in a private home that doubles as a museum of Egyptology, and the solution depends in part on Vance's extensive knowledge of Egyptian history and customs, which enable him to sort through suggestions of godly vengeance and reveal the misdirections perpetrated by the real murderer.
